The component in bold is the one you are currently viewing.


The forecast section offers a wide range of atmospheric and wave models, including our own in-house models. In the free (test)version of I'm Weather you only have access to GFS and GFS-WAVE. The one in green is the model you are currently viewing. When you have selected a model, you will find:

On the right side you can set the model parameter. To view all available parameters for this model, click on the "more ∨" button. At the bottom you can change the weather model and the model run. In general you will find the latest four model runs per model. Also, there is the timestep selection bar. Click on it to go to a certain forecast timestep. There is also a 'play' functionality to see the forecast develop in time. If you click on the map or search for a location a horizontal bar below the timestep selection bar appears. Click on this bar and the timeseries feature will open. This gives a forecast overview for multiple parameters in time for that location. Note: a more in detail article about what you can do with these timeseries will be written later.


The nowcast section is about current weather. The main features are precipitation, clouds, and lightning.
I'm Weather nowcast
For precipitation we offer the most up-to-date radar images, and if radar does not cover an area, we use satellite techniques to detect precipitation intensity and type. For clouds we use a variety of satellite images for the entire world in various channels: visible light, infrared, combined day/night image, and special night-microphysics images for detecting fog and low clouds. Lightning is presented near real-time and based on data from a worldwide network of lightning sensors.
